高速永磁电机系统因其在功率密度、调速范围和动态性能等方面的特有优势，可用于数控机床、机器人、电动汽车、航空航天以及工业压缩机等高端装备领域，应用前景广阔，近年来已成为国际电机领域重要研究方向之一。高速永磁电机系统运行控制过程中参数非线性扰动更突出，高速下单个电周期内控制频次下降更明显，严重影响系统整体控制性能，因此研究高性能控制算法是保证高速永磁电机系统高品质运行的关键。本项目则是在此背景下开展研究工作，基于过采样理论构建多参数分时辨识架构，提出单矢量组合周期内控制输出滚动优化与开关模式动态调控方法，将智能算法与电机核心算法通过多层控制架构实现离线设计与实时控制的统一，运用稳健性理论分析并校核系统控制算法，最终将进一步完善电机系统过采样控制理论，提出一套完整的智能化分时动态调控方法，使高速永磁电机系统在全速域全负载范围内保持均衡、稳定且一致的动稳态性能。

Because of the unique advantages of high-speed permanent magnet (PM) motor system in power density, speed adjusting range and dynamic performance, it can be used in high-end equipment fields such as numerical control machine, robot, electric vehicle, aerospace, ship propulsion system and industrial compressor, and will be better in application prospects. The high-speed permanent magnet motor system has become an important research. In the operating process of high-speed PM motor system, nonlinear perturbation of parameters is more prominent, and the control times decrease more obviously in a single electric cycle at high speed, that will seriously affect the whole control performance of the system. Therefore, it is important to research the high-quality control algorithm for guaranteeing the high-performance of the high-speed PM motor system operation. Under this background, this project carries out research work. We will construct a multi-parameter time-sharing identification architecture based on oversampling theory, propose a method with control output rolling optimization and switching mode dynamic control in single vector combination cycle, integrate intelligent algorithm and motor core algorithm by multi-layer control architecture to achieve the unification of off-line design and real-time control, analyze and verify the system control algorithm with robustness theory, and ultimately the oversampling control theory of motor system will be further improved. We will propose a complete intelligent time-sharing dynamic control method to maintain the balanced, stable and consistent dynamic and steady-state performance of high-speed PM motor system in the full speed range and full load range.
